Description of key information

A melting range of 420-480°C was determined for cesium tetrafluoroaluminate. 

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
420 °C

Additional information

One reliable key study is available for this endpoint. In this study the melting point of cesium tetrafluoroaluminate was measured by a Differential Thermal Analysis (DTA) combined with a Thermal Gravimetry (TG) in accordance with the OECD Testing Guideline 102 (Solvay SA, 2013a).

A melting range between approx 420-480°C was observed for cesium tetrafluoroaluminate. The substance decomposes at temperatures above 550°C.
